Sorry, sent the previous message incorrectly.

I would like to fill down so only one character changes sequentially, like
this:

C:\Documents and Settings\User\My Documents\Pictures\1.jpg
C:\Documents and Settings\User\My Documents\Pictures\2.jpg
C:\Documents and Settings\User\My Documents\Pictures\3.jpg
C:\Documents and Settings\User\My Documents\Pictures\4.jpg

Any assistance is appreciated.
